Cara Delevingne confirms that she's been dating Ashley Benson for a year

There's been lots of speculation about the couple, but Delevingne only confirmed the relationship on June 15, when she shared a video on Instagram in which she was kissing the actress.

On Monday night, Delevingne was on the red carpet for the TrevorLIVE Gala in New York City and was asked about her choice to go public with her relationship. She said there were two main reasons: her one-year anniversary with Benson and the 50th anniversary of the Stonewall Riots.

"I don't know [if it's] because it is Pride, it's been 50 years since Stonewall happened and I don't know," she explained. "It's been just about our one-year anniversary so, why not?"

While accepting the Hero Award at the event, the English model spoke about her American girlfriend in her speech.

"I also have another very special woman in this room to thank and you know who you are," she said, addressing Benson. "She's one of the people who helped me love myself when I needed it most and I really needed it. She showed me what real love is and how to accept it, which is a lot harder than I thought."

Meanwhile, the actress told reporters at the event that producers once said her sexuality would hurt her career.

"Behind closed doors, we are still being told, as I have, by powerful Hollywood producers that we can't make it if we're queer," Delevingne said, according to Variety. "We're told that we're not normal, that we're undeserving of love even by the ones we're supposed to love the most."

Recently a source told E! News that the couple are "very sweet and loving together."

"They are always doing simple nice things for each other and it all comes very easy and naturally," said the insider. "They are committed to one another and very much in love."
